I have lost my saved my player.

Lost my campaign save file twice now for no reason now LOST the will to play single player campaign now would no doubt keep happening

as others have, i tried to reinstall the game and clear all my saved data but didn't work. the solution about changing arena player did work, unfortunatley because i deleated all saved game data i lost all my ultimate team players that i had bought through
player packs and i can't get them back so that money was wasted. definatley try changing the arena player before you wipe all your saved data.

Unfortunately, this game doesn't have a cloud save. Before you formatted your PC you should have saved the game save file. Maybe the developer can do something but it's pretty unlikely.

im concerned i have done the story on insane and i have the medals and achievements to prove it but last week i lost my single player save file. so now the game acts like i have never played it before.

Hope you're doing great today despite this Marco

I don’t like to give bad news but if the last saved progress doesn’t appear this means that something went wrong with that :c

To avoid a similar situation in the future I can advise you to manually backup the save files
